Who knew resting could do that much damage?

Snake: Aw, there's a huge eyeball walking around here...
Colonel: That's just Jigglypuff.
Snake: Jigglypuff? That some kind of marshmallow?
Colonel: Jigglypuff is a balloon-shaped pokémon.
It might be light and puffy and full of air, but its Sleep ability is devastating.
Snake: Sleep...? What's so devastating about it going to sleep?
Colonel: The instant it falls asleep, there's a huge buildup of energy in its center of gravity. If it hits you, its lights out for sure.
Snake: So it puts a lot of energy in to sleeping? Sounds pretty irresponsible if you ask me.
Colonel: It takes all kinds, Snake. Especially here in "Brawl."
